Try booting on safe mode. And see if that helps.

Given the nature of the issue, I would advise running a firmware repair.

Please note that performing these steps will delete all user data except for your media files (photos, music and video).

If your handset is able to be powered on and unlocked you can follow the below steps to back-up your personal data prior to running the repair.

Backing up your handset

1. Go to Support  to install PC Companion on a Windows computer. 
2. When installed, start PC Companion on the computer. 
3. Connect your phone to the computer using a USB cable.

5. Follow the on-screen instructions.

Exactly what contents will be backed up may differ depending on phone model.
You can view detailed information about this as you follow the steps in the Backup & Restore wizard.

Have you changed the Stamina Mode Activation to 100% ?

Because it will only start working once it reaches its minimum threshold point.
